RAFFLE MEANS FOR 'FIRE-fiGlliiEE lication filed February 20, 1914.

To al whom it may 0011mm:

Be it known that I, Enoon P. STEVENS. a eitizeu of the United States,residing: at (hirago. in the county of Cook and State of Illinois. haveinvented certain new and useful Improvements in Baffle Means for Fire-Boxes. of which the following is a speeilieae tion. 7

My invention relates to baffle means for fire-boxes. and refersparticularly to baflle means to he used Within the fire-boxes ofrfORl-lfllllliflfl loeoi'iuitives.

lo man classes of lmi-'m'ioti\'es fire-lu'iek air-Les are use-l For theour-pose ol delierting the prorl'uels of eolnhustion in oriler to prvide a longer path through \rliieli such proil" uris must pass lie'foreentering the boiler fines. In many eases it is usual to support sucharr-lies on \vaier-eoolerl arch tubes wliieh rrteurl u umrellv andrearwardly of the tireinn: from the flue sheet thereof.

In many loeon'iotires it is (lillieult. if not impossible. to employsupporting arch tulies. on'ac-eouut of the dimensions of the firebox. Itis to loeomotives of this character that niv invention is directed.

My hallle nuuns consist of one or more he siile sheets nlul beingarranged in a sulr linlially Iviilr'fll plane. so that the gases 'miuisiion are (iiilPCtOti before entering the lioilrr lines. 1 prefer toemploy two of lmfile walls. me, front one of which is l wateil higherthan the rear one. but 1 lo n t routine myself to any purtieular number:1!" illl hal l Walls, as one or a greater nlunher than two wouldreadily he ein iiloyerl.

li, is a Further ohieet of nrv imention to empl y S'urlu a eonsiruelionthat each of the "llle walls nun lie oonstrur'rterl of a pluralitv i.luieks or tiles \rhieh are securely loelrerl iogether in order to retaintheir position in th lire-non.

A still further object of my invention consists in providing the halllewalls with passages anil apertures through which air, steam. or othergases. XUEIV he riiseliargerl in ord r to pr mote eoinhustion and toeonsume smoke. Such gases areintrodueed into the hafile Walls throughthe supporting means loeated on the side sheets of the fire-box.

These and other advantages of my invention will be more readilyunderstood by sueli Specification of Letters Patent.
